The amount of fabric is subject to typesetting. After typesetting, you will get the unit consumption of each garment, which can be saved by increasing the width of the fabric or adjusting the typesetting method. Unit consumption * total number of pieces * loss (generally 2%, which will change according to different styles) = total consumption.

In fact, the auxiliary materials are almost the same, and the consumption of a single piece * total number of pieces * loss = total consumption.
